5. Raphael: Jensen Ackles
Raphael has always been the angry, troubled brother, jockeying with Leonardo over the leadership of the Turtles. Someone who I think has the voice for a dark, angry character is Jensen Ackles. Ackles’ role as Dean on Supernatural consists of a varying array of deep growls and grunts, and that added with his uncanny talent to play characters who have chips on their shoulders is the perfect recipe for Raphael.
